What is the function of the hepatic cecum?
It is apparent that the hepatic cecum performs important roles in the immunity of amphioxus including immune surveillance, clearance of pathogens and acute phase response. Therefore, the hepatic cecum, like the vertebrate liver, is an organ functioning as a key integrator of immunity in amphioxus.
What is the function of the pyloric caeca in a starfish?
With the stomach inside, the starfish digests the mollusk in the shell. The pyloric stomach is connected by two pyloric caeca- hollow tubes that absorbs nutrients from its food.
What is the function of hepatic caeca in cockroach?
In cockroach, the hepatic caeca is present at the junction of the foregut and midgut. It is a ring of 6-8 blind tubules. Their function is to secrete digestive juices to facilitate digestion.
Which of the following can be absorbed by hepatic caeca?
So the correct answer is ‘Glucose and amino acids’.
What is the function of a starfish?
So starfish are predators, and they’re probably the most important predator in the shallow ecosystem – so the depths where we would dive or swim. They eat basically anything that they can come across. Their feeding activities control the whole ecosystem.
What is the function of gizzard in cockroach?
Hindgut: Its main function is the absorption of water and minerals. So, the correct answer is, ‘the function of gizzard seen in grasshopper and cockroach digestive systems is grinding of food materials’. Note: The main function of the gizzard is grinding the food and not storage.
What is the role of Alary muscles in cockroach?
Hint: Alary muscle in cockroaches occurs in the heart wall and it helps in blood circulation. Alary muscles are associated with the blood vascular system of cockroaches.
What is meant by hepatic caeca?
Hepatic caecum or hepatic cecum is a name used in describing various physiological structures in some crustaceans, insects and cephalochordates. “Hepatic” refers to the liver, and the hepatic caecum may perform some functions that are analogous to the functions of the liver in vertebrates.
How many hepatic caeca are there in cockroach?
This marks the end of foregut. – The midgut is a coiled tubular structure. At the junction of foregut and midgut, there are 4-6 fingerlike structures called hepatic caeca.
What is meant by hepatic Caeca?
Is the hepatic caecum the same as the liver?
How does the cecum function in an omnivore?
Animals, both herbivores and omnivores, take in cellulose when eating plants. Bacteria and enzymes in the cecum of these animals cause fermentation that breaks down cellulose fibers, which then allows the rest of the large intestine to digest the nutrients from cellulose. The cecum functions differently in various animal species.
Where is the cecum located in the digestive system?
Cecum location Anatomically connecting the ileum and ascending colon via the ileocecal valve, the cecum receives digested chyme with intestinal fluid and begins to absorb water and other nutrition physiologically 1). Therefore, it is anatomically and physiologically a transition site for digestive function.
Where is the hepatic caeca located in a cockroach?

In cockroach, the hepatic caeca is present at the junction of the foregut and midgut. It is a ring of 6-8 blind tubules. Their function is to secrete digestive juices to facilitate digestion.
Why does a starfish not have a circulatory system?
The pyloric cecum at each of the arms of the starfish supplies nutrients to all parts of the body as well but does not form a system. That is why circulatory system is not a true system and they do not have one while humans need the blood, heart, arteries and veins to perform that function.

Is the hepatic caecum part of the digestive system?
The hepatic caecum is a name given to various digestive structures found in certain crustaceans.
